|

$CMDNAME is a utility to start, stop, restart, and report the status
|
||||
of a PostgreSQL server.
|
||||
|
||||
Usage:
|
||||
$CMDNAME start [-w] [-D DATADIR] [-p PATH-TO-POSTMASTER] [-o \"OPTIONS\"]
|
||||
$CMDNAME stop [-w] [-D DATADIR] [-m SHUTDOWN-MODE]
|
||||
$CMDNAME restart [-w] [-D DATADIR] [-m SHUTDOWN-MODE] [-o \"OPTIONS\"]
|
||||
$CMDNAME status [-D DATADIR]
|
||||
|
||||
Options:
|
||||
-D DATADIR Location of the database storage area
|
||||
-m SHUTDOWN-MODE May be 'smart', 'fast', or 'immediate'
|
||||
-o OPTIONS Command line options to pass to the postmaster
|
||||
(PostgreSQL server executable)
|
||||
-p PATH-TO-POSTMASTER Normally not necessary
|
||||
-w Wait until operation completes
|
||||
|
||||
If the -D option is omitted, the environment variable PGDATA is used.
|
||||
|
||||
Shutdown modes are:
|
||||
smart Quit after all clients have disconnected
|
||||
fast Quit directly, with proper shutdown
|
||||
immediate Quit without complete shutdown; will lead
|
||||
to recovery run on restart
|
||||
|
||||
Report bugs to <pgsql-bugs@postgresql.org>."
